The Impact of Disease Registries on Advancing Knowledge and Understanding of Dementia Globally

To help address the increasing challenges related to the provision of dementia care, dementia registries have emerged around the world as important tools to gain insights and a better understanding of the disease process. Dementia registries provide a valuable source of standardized data collected from a large number of patients. This review explores the published research relating to different dementia registries around the world and discusses how these registries have improved our knowledge and understanding of the incidence, prevalence, risk factors, mortality, diagnosis, and management of dementia. A number of the best-known dementia registries with high research output including SveDem, NACC, ReDeGi, CREDOS and PRODEM were selected to study the publication output based on their data, investigate the key findings of these registry-based studies. Registries data contributed to understanding many aspects of the disease including disease prevalence in specific areas, patient characteristics and how they differ in populations, mortality risks, as well as the disease risk factors. Registries data impacted the quality of patients’ lives through determining the best treatment strategy for a patient based on previous patient outcomes. In conclusion, registries have significantly advanced scientific knowledge and understanding of dementia and impacted policy, clinical practice care delivery

Cognitive rehabilitation for early stage Alzheimer’s disease: a pilot study with an Irish population

Objectives Research shows that cognitive rehabilitation (CR) has the potential to improve goal performance and enhance well-being for people with early stage Alzheimer’s disease (AD). This single subject, multiple baseline design (MBD) research investigated the clinical efficacy of an 8-week individualised CR intervention for individuals with early stage AD. Methods Three participants with early stage AD were recruited to take part in the study. The intervention consisted of eight sessions of 60–90 minutes of CR. Outcomes included goal performance and satisfaction, quality of life, cognitive and everyday functioning, mood, and memory self-efficacy for participants with AD; and carer burden, general mental health, quality of life, and mood of carers. Results Visual analysis of MBD data demonstrated a functional relationship between CR and improvements in participants’ goal performance. Subjective ratings of goal performance and satisfaction increased from baseline to post-test for three participants and were maintained at follow-up for two. Baseline to post-test quality of life scores improved for three participants, whereas cognitive function and memory self-efficacy scores improved for two. Conclusions Our findings demonstrate that CR can improve goal performance, and is a socially acceptable intervention that can be implemented by practitioners with assistance from carers between sessions. This study represents one of the promising first step towards filling a practice gap in this area. Further research and randomised-controlled trials are required

Visual short-term memory binding deficit with age-related hearing loss in cognitively normal older adults

Age-related hearing loss (ARHL) has been posited as a possible modifiable risk factor for neurocognitive impairment and dementia. Measures sensitive to early neurocognitive changes associated with ARHL would help to elucidate the mechanisms underpinning this relationship. We hypothesized that ARHL might be associated with decline in visual short-term memory binding (VSTMB), a potential biomarker for preclinical dementia due to Alzheimer’s disease (AD). We examined differences in accuracy between older adults with hearing loss and a control group on the VSTMB task from a single feature (shapes) condition to a feature binding (shapes-colors) condition. Hearing loss was associated with a weaker capacity to process bound features which appeared to be accounted for by a weaker sensitivity for change detection (A’). Our findings give insight into the neural mechanisms underpinning neurocognitive decline with ARHL and its temporal sequence

Exploratory study of the teaching of neuropsychology in the curricula of undergraduate courses in Speech-Language Pathology

Objetivo: Identificar a presença do ensino da neuropsicologia nos cursos de graduação em fonoaudiologia no Brasil através de uma análise exploratória dos currículos dos cursos de graduação. Método: Estudo documental exploratório quantitativo. Foi realizada uma busca de documentos (projeto pedagógico de curso, ementário e/ou matriz curricular) nos websites das instituições de ensino superior públicas e privadas, ou via e-mail. A busca das informações necessárias para o estudo foi feita por três pesquisadores através de um checklist elaborado em consenso. Dessa maneira, pôde-se caracterizar as instituições de ensino e, posteriormente, foram investigadas quais delas ofereciam disciplinas que abordassem o tema da neuropsicologia através de uma busca pelo nome da disciplina. Foram exploradas associações entre a natureza da instituição de ensino superior, ano do projeto pedagógico de curso e região demográfica, com a presença de disciplinas sobre neuropsicologia. Resultados: Foram incluídas no estudo 72 instituições de ensino, sendo que destas apenas nove ofereciam a disciplina de neuropsicologia. Nenhuma das associações testadas gerou diferença estatisticamente significativa. Conclusão: Há uma carência na oferta de disciplinas de neuropsicologia para os estudantes de fonoaudiologia, e esta carência não tem relação nenhuma com a natureza da instituição de ensino superior, o ano do projeto pedagógico de curso ou com a região demográfica. Os achados chamam a atenção para a importância de um currículo que considere todo o escopo de atuação profissional e se ajuste à epidemiologia dos distúrbios da comunicação.Purpose: To determine the level of teaching of neuropsychology within undergraduate courses of speech-language pathology in Brazil using an exploratory document analysis of the curricula of the undergraduate courses. Methods: It is a quantitative exploratory document analysis. A review of available documents from websites and/or received from course directors (pedagogical course project, course content, and/or syllabus) of public and private universities in Brazil was carried out. Using an agreed consensus checklist, 3 researchers verified which universities offered subjects on neuropsychology by means of a search for the term ‘neuropsychology’ or neuropsychological’. Associations between type of university and region and the provision of neuropsychology courses were also explored. Results: 72 universities were included in the study and only nine of them offered subjects on neuropsychology. None of the associations tested was statistically significant. Conclusion: The provision of neuropsychology for speech-language pathology undergraduate students is limited, and not associated with the type of university, the year of the pedagogical course project, or the region in which the university is located. The findings call attention to the need to adapt undergraduate curricula in speech-language pathology to consider the entire scope of this profession and address the epidemiology of communication disorders

A preliminary study of the effects of nighttime administration of the serotonin agonist, m-CPP, on sleep architecture and behavior in healthy volunteers

The effects of m-chlorophenylpiperazine (m-CPP) (0.5 mg/kg) on sleep architecture and behavior were examined in six healthy volunteers following a single or oral dose of the drug in a randomized, double-blind, placebo-controlled study, m-CPP reduced total leep time (TST) and sleep efficiency in all subjects. Slow-wave sleep (SWS) and rapid-eye-movement (REM) sleep were decreased and stage 1 sleep was prolonged in a majority of subjects. Prominent behavioral and psychological effects were reported in five out of six subjects following m-CPP (but not following placebo) that interfered with sleep. The sleep disruption and behavioral activation following nighttime administration of m-CPP contrasts with the sedative properties of its parent compound, trazodone, suggesting that the hypnotic effect of trazodone is not related to the agonist profile of its metabolite, m-CPP.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29486/1/0000572.pd
